Title: Stable blood platelet reference sample - obtd. by addition of a solid polyethylene glycol to the suspension of platelets or to a diluent for platelets
Inventor: RYAN WAYNE LEO
IPC: G01N33/96
Filed: 1978-11-14
Abstract: Stabilised reference sample for the counting of blood platelets, is obtd. by addn. of a solid polyethylene glycol to a suspension of the platelets and then adding the other constituent to the mixture resulting from the first addn. to give a sample which is stable with time and upon shaking. When the polyethylene-glycol is added to the suspension pref. 10-20 g. of polyethylene-glycol are added per 100 ml of suspension.

Patent DE-2912748-A1 (DE)
Inventor: KOENIG HELMUT DR ING
IPC: B61J3/00
Filed: 1979-03-30
Abstract: An advancing speed of the shunting locomotive which is pushing the train is determined for moving on trains to the hump of a railway shunting system, which speed permits on the one hand a prompt shunting of the train to the hump but at the same time ensures that the train comes to a stop before the summit of the hump if the gravity-shunting system has not yet been cleared for the said train. The acceptable advancing speed is determined from system-specific and train-specific data which can be determined with sufficient accuracy. Conformance with the respectively determinable advancing speed enables the highest possible gravity-shunting capacity of the shunting system to be achieved.
